Summer is here, and with it comes the relentless presence of filth flies. Despite their small size, these pests can create big problems for your business, from undermining sanitation standards to tarnishing your hard-earned reputation. With a life cycle that’s astoundingly fast — eggs can hatch in as little as 24 hours, and female flies lay hundreds or even thousands of eggs each month – understanding how to prevent filth flies in your business is extremely important.

While it may seem overwhelming, it’s entirely achievable as long as you have a proactive and well-structured commercial fly prevention strategy. To get started, the basics of fly prevention revolve around:

Sanitation and waste management
Physical exclusion
Monitoring and eliminating breeding sites
Environmental controls

Summer Fly Prevention Tips

As a leader in pest control in Wisconsin since 1946, Batzner Pest Control has gained a deep understanding of fly biology and behavior, and how those apply to infestations in businesses and facilities like yours. Let’s run through the key components of fly prevention in businesses, with some easy suggestions for improvement in each area.

Sanitation and Waste Management

Flies are strongly attracted to organic matter such as food waste and residue. Establishing rigorous sanitation protocols is your first line of defense against fly infestations. Here are a few key recommendations for effective sanitation and waste management to keep flies out.

Keep trash bags securely sealed or in tightly fitting trash cans.
Regularly empty and clean dumpsters to remove organic matter.
Immediately clean food spills and maintain routine deep-cleaning schedules, particularly in kitchens and dining areas.
Schedule weekly drain cleanings, especially for drains servicing beverage stations.
Clean drip trays of fountain beverage machines daily.
Ensure kitchen and bar equipment, server stations, tables, and floors are thoroughly cleaned every day.
Properly store mops and buckets to facilitate drying and prevent moisture buildup.
Frequently clean beneath cooking equipment and prep stations.
Promptly eliminate standing water using mops or floor drying fans.
Dispose of decaying produce and food waste daily.

Physical Exclusion

Flies are adept at exploiting even tiny openings. Physical exclusion involves creating physical barriers and sealing entry points to prevent them from being able to do so. It’s an often overlooked but highly important part of fly prevention.

Install and maintain tight-fitting screens on all windows and vents.
Keep exterior doors closed when not in use; consider air curtains at main entrances.
Seal cracks and gaps around windows, doors, and utility penetrations.
Ensure tiles are in place and grout intact to prevent debris accumulation.
Use screens with at least 18 squares per inch mesh density.
Ensure positive airflow at all entrance and exit points.
Seal openings around pipes, cables, and wires with caulk, screening, or steel wool.
Install weather stripping and door sweeps to eliminate entry gaps.

Monitoring and Eliminating Breeding Sites

Many businesses unknowingly harbor breeding sites within their facilities, providing perfect conditions for flies to thrive. Identifying breeding sites and actively monitoring them can help prevent fly populations from exploding.

Remove standing water and organic debris around your property, focusing on floor drains, grease traps, and moisture-prone areas.
Regularly inspect for and clean potential hotspots like cracks in floors, grout lines, and areas around beverage stations and food prep equipment.
Recognize indoor breeding sites such as small cracks and crevices where organic debris can accumulate unnoticed.
Pay attention to outdoor breeding sites for larger flies, such as garbage, animal waste, and rotting materials.

Environmental Controls

Adjusting environmental conditions within your business can significantly reduce fly activity. Proper airflow, controlled humidity, and strategic waste management positioning all contribute to creating an inhospitable environment for flies.

Maintain adequate ventilation and optimal humidity levels to deter flies.
Place dumpsters and waste receptacles away from main building entrances whenever possible.
Use dehumidifiers and fans to reduce moisture and circulate air.
Keep all garbage receptacles closed, clean, and emptied at least twice weekly, especially in warmer weather.

What Is a Filth Fly, Anyway?

The term “filth fly” broadly refers to any fly species that thrives in unsanitary conditions and has the potential to spread pathogens. Due to their resilient nature, these flies can survive and breed in minimal organic matter, from food residues to drainage systems.

Common types of filth flies include:

Should You Worry About Flies at Your Business?

Absolutely. Flies pose significant health risks, contaminate food and surfaces with harmful bacteria, and negatively impact customer perceptions. Businesses in food service, hospitality, healthcare, and education sectors particularly face heightened risks.

Key reasons why flies are dangerous for businesses:

Potential illness for employees and customers due to the spread of bacteria and pathogens
Contaminated or destroyed products or inventory
Possible penalties from failed sanitation and health inspections
Devastating damage to your reputation and customer trust, impacting your bottom line

Types of Businesses That Should Invest in Fly Prevention

Fly infestations are bad news for any business, but especially those that store, process, or sell food. In food service and food processing businesses, fly infestations are a major problem that can jeopardize product safety. To effectively manage flies, it’s strongly advised that these businesses work with a professional fly prevention and control company:

Grocery Stores and Supermarkets: Exposed to fly infestations because of fresh produce and food displays.
Food Processing Facilities: Require stringent hygiene protocols to prevent fly breeding near food products.
Hotel and Hospitality: Face fly challenges due to food services, waste disposal, and guest traffic.
